From: Julia Lawall <julia@xxxxxxx> Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more clear what is the purpose of the operation, which otherwise looks like a no-op. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ type T; T x; identifier f; @@ T f (...) { <+... - ERR_PTR(PTR_ERR(x)) + x ...+> } @@ expression x; @@ - ERR_PTR(PTR_ERR(x)) + ERR_CAST(x) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- ipc/sem.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -u -p a/ipc/sem.c b/ipc/sem.c --- a/ipc/sem.c +++ b/ipc/sem.c @@ -1069,7 +1069,7 @@ static struct sem_undo *find_alloc_undo( /* step 1: figure out the size of the semaphore array */ sma = sem_lock_check(ns, semid); if (IS_ERR(sma)) - return ERR_PTR(PTR_ERR(sma)); + return ERR_CAST(sma); nsems = sma->sem_nsems; sem_getref_and_unlock(sma); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
